Connection examples
Before you can connect the cables to the
amplifier, you must first detach the top half
of the housing shell (see "Removing the out-
er housing").

+12V
The switching line must be connected when
connection is carried out using the RCA jacks
or the loudspeaker jacks of the car radio.
Tri mode
You can operate 2 loudspeakers and at the
same time switch on a third loudspeaker in
mono mode (bridge mode) (see Fig. 10).
GAIN control
You can use the GAIN control to adjust the
input sensitivity of the Blaupunkt power am-
plifier to the output voltage of your car ra-
dio's preamp output.
The setting can be adjusted between 0.3 V
and 8 V.
When connecting a car radio produced by
another manufacturer, you must adjust the
input sensitivity in accordance with the in-
formation provided by the manufacturer.
Please note that the GAIN control is not a
control for adjusting the volume!

INPUT
Preamp inputs for the right and left chan-
nels. Please use high-quality Blaupunkt RCA
cables for this connection.
LP / HP / FULL switch
Before installing, adjust the X-OVER switch
on the power amplifier to set the low pass
filter (LP), high pass filter (HP) or full-range
setting (FULL). If you select the FULL posi-
tion, the full frequency response will be used.
Using the integrated crossovers is particu-
larly useful in the case of multi-channel
sound systems with a separate subwoofer.
In order to obtain the best sound when a
subwoofer is connected, the subwoofer must
be separated as far as the frequencies it re-
ceives are concerned, i.e. it must only be
fed with low frequencies (bass).
To ensure that this is the case, select LP and
use the crossover frequency control to ad-
just the upper frequency to between 50 Hz
and 250 Hz. This ensures that every sub-
woofer is optimally separated as far as the
frequencies it receives are concerned.
If HP is selected, you can use the associat-
ed crossover frequency control to adjust the
lower cut-off frequency to between 50 Hz and
250 Hz.
If you want to precisely optimise the acous-
tic settings of the crossover, we recommend
you obtain advice from a Blaupunkt dealer.
It is very important that you take into ac-
count the specifications of the loud-
speakers being used whilst you are ad-
justing the crossover.
